We have been creating a content management system in Django which
(despite a few learning bumps) has gone swimmingly. Now, we have
reached an impasse. We have some applications running elsewhere on the
site whose xml data we need to access and display from a django view
function. We read through and experimented with a variety of tutorials
(since we're all still very new to python) and found several approaches
that seem to work when written in the shell. Adding them to django
however has proved to be very difficult. Regardless of what we try, it
seems impossible to get django to kick out the information we want or
even to have it generate an error message that would give us some kind
of feedback. The current iteration that we have experimented with looks
like this (a shameless ripoff from the Python Cookbook):
from xml.sax import make_parser
from xml.sax.handler import ContentHandler
def catalog(request):
class countHandler(ContentHandler):
def __init__(self):
self.tags = {}
def startElement(self, name, attr):
self.tags[name] = 1 + self.tags.get(name,0)
parser = make_parser()
handler = countHandler()
parser.setContentHandler(handler)
parser.parse("/usr/web/www/test.xml")
tags = handler.tags.keys()
tags.sort()
datum = ""
for tag in tags:
datum = "%s<br />%s - %s" % (datum, tag, handler.tags[tag])
return render_to_response('templates/generic_output.html',
{'output':datum})
We have also tried using minidom with no success. Any pointers in the
right direction would be incredibly helpful.
Thanks,
Mike
